hm ............ a puzzlePosted by Catherine Cartwright-Jones on July 7, 2004 at 10:39:37: In reply to: Re: Thanks and questions posted by Diane on July 6, 2004 at 18:18:49: Lawsone (henna's dye molecule) is orange. It can oxidize to thedarker colors ......... Hm............... variations in gray hair ........... another puzzle. I see a long stretch in the academic journals again. My gray does just fine with henna. I have noticed that my husband's gray beard hairs are straighter than the rest of his beard hairs (black person, kinky hair). I wonder if I can get him to spare a few of each for comparison. I wonder if I can get a better microscope for Christmas.
